CUSHION-FRAME FOR BICYCLES 0R LIKE VEHICLES.

4 SPECIFICATION forming part of Letters .Patent No. 707,262, datedAugust 19, 1902.

Application filed January 18. 1902. Serial No. 90,286. (No model.) l

To @ZZ whom it may concern:

Beit known that we, JAMES H. SAGER and GEORGE D. GREEN, citizens of theUnited States, and residents of Rochester, in the county of Monroe andState of New York, have invented certain new and useful Improvements inCushion-Frames for Bicycles or Like Vehicles, of which the following isa specification.

This invention relates to cushion-frames for bicycles and like vehicles,and has for its object to relieve riders of such vehicles from thejarring and shaking ordinarily occasioned by rough roads andobstructions encountered i the road.

The peculiar features of the invention are disclosed in the drawings andare particularly pointed out in the following-specification.

Figure 1 of the drawings shows in side elevation a part of the fra-me ofa bicycle, the position of the rear wheel and the location of certainparts being indicated by dotted lines; and Fig. 2 is partly a section onthe line 2 2 of Fig. l and partly a rear View of a portion of the framebroken away, so as to show the construction.

A represents the front section of the frame, with the exception of thehead, which is not shown.

B is the horizontal barrel, `which is the crank-hanger; C, therear-wheel fork, which D the rear braces, which are each iiexiblyconnected with a member of the fork C,as by the bolt d.

D' is a brace for the rear braces D. The hanger B, the fork C, and thebraces D constitute what will hereinafter be referred to as the rearsection of the frame. The front and rear sections of the frame areiiexiblyy connected at the hanger B, as by ears b and the bolt b. Thesections of the frame are also flexibly connected at the upper ends ofthe braces. A clip or bracket E, rigidly' secured to the front section,supports a crossbar whose ends rest upon springs within the braces D D.This cross-bar is in the construction shown composed of the blocks F F,which are supported by means of arms G G, respectively, which in turnlie within the socket e in the clip E and which are adjustably fastenedtogether, as by the screw g. The blocks F F are adapted to lit withinthe tubular braces D, respectively, so as to slide freely within them,and are enabled to slide within said braces by the longitudinal slots dd', which receive and permit the passage of the arms G G, respectively.At the point where thearms G G join the rods F they are cut down, asshown in Fig. 2, so that the slots d CZ may be narrower lthan theyotherwise would be.

The adjustable connection of the. blocks F F, as by means of the lscrewg, obviates the necessity of accuracy in the construction of the armswithY reference to the distance between the braces D D which otherwisewould 'be necessary in order to secure the eifective operation of said`blocks within said braces. The separableconnection within the arms G Gafforded by thescrew g also enables the parts to be readily assembledand taken apart.

Within the tubular braces D D are respectively two coiled-springs H H,which may be seated at the lower ends of said braces, respectively, orin any suitable manner, as on a pin d3. (See Fig. l.) The tubular bracesD D are represented as straight and parallel for their full length inorder that springs of maximumilength maybe employed. The upper ends ofthese springs lie, respectively,

against the blocks F F and are preferably under slight tension when intheir normal position, (shown in Fig. 2,) so that the parts will notrattle. Stops of suitable form, such .as caps D2 D2, are screwed intothe tops of the tubes D D, respectively, and a packing cl2 d2, ofrubberor other suitable material, is placed within said tubes D D,respectively, beneath the caps D2 D2 to receive the rebound oft-theblocks E E when the springs H H are relaxed. y

The operation 4of the device is as follows:

When by reason of the roughness of the roadV or of an obstructionencountered by the wheels the weight of the rider is brought suddenlyupon the frame, the front section will turn upon its lower pivotalconnection with the rear section at the hanger and the blocks F F willsink down into the tubular braces D D against the yielding resistance ofthe springs H H, said tubular braces and blocks F F at the same timealining themselves to IOO each other by turning at the point Where theyare respectively connected iiexibly with the fork C and the bracket E.By this construction very long coiled springs maybe employed which willgive great elasticity to the frame, for the springs may, if desired, beextended down into said braces for practically their whole length, andat the same time a construction is had in which the seat-post and saddlecan be placed Well down upon the frame.

What we claim is- 1. The combination of a rigid front section; arear-Wheel fork flexibly connected therewith at the cran k-hanger;tubular rear braces flexibly connected with said fork; a slot in each ofsaid braces at its upper end; a spring Within each of said braces; aseat for the bottom of each of said springs; a cross-bar flexiblyconnected With the front frame and passing through said slots; a blockWithin each of said braces resting on the spring in the brace andsecured to said bar and free to slide Within said brace; and a stop ineach brace above the block.

2. The combination of a rigid front section; a rear-Wheel fork fiexiblyconnected therewith at the crank-hanger; parallel tubular bracesflexibly connected with said fork; a slot in each of said braces at itsupper end; a spring Within each of' said braces; a seat for the bottomof each of said springs; a crossbar flexibly connected with the frontframe and passing through said slots; a block within each of said bracesresting on the spring in the brace and secured to said bar and free toslide within said brace; and a stop in each brace above the block.

3. The combination of a rigid front section; a rear-wheel fork iexiblyconnected therewith at the crank-hanger; tubular rear braces flexiblyconnected with said fork; a slot in each of said braces at its upperend; a spring within each of said braces; a seat for the bottom of eachof said springs; an adjustable cross-bar flexibly connected With thefront frame and passing through said slots; a block Within each of saidbraces resting on the spring in the brace and secured to said bar andfree to slide Within said brace; and a stop in each brace above theblock.

4;. The combination of a rigid front section; a rear-Wheel fork flexiblyconnected therewith at the crank-hanger; tubular rear braces flexiblyconnected With said fork; a slot in each of said braces at its upperend; a spring Within each of said braces; a seat for the bottom of' eachof said springs; a separable crossbar fiexibly connected with the frontframe and passing through said slots; a block within each of said bracesresting on the spring in the brace and secured to said bar and free toslide within said brace; and a stop in each brace above the block.

5. The combination of a rigid front section; a rear-Wheel fork flexiblyconnected therewith at the crank-han ger; tubular rear braces flexiblyconnected with said fork; a slot in each of said braces at its upperend; aspring Within each of said braces; a seat for the bottom of eachof said springs; abracket rigidly connected With the front frame; anadjustable crossbar revolubly supported Within said bracket and enteringsaid slots; a block within each of said braces resting on the spring inthe brace and secured to said bar and free to slide within said brace;and a-stop in each brace above the block.
